BUNDLE BINDING Allin TYIIING MACHINE.

To all whom it may concern:

Be it known that I, CHARLES E. EvANs, a citizen of the United States,and resident of the city of Seattle, county of King, State 6 ofWashington, have invented certain new and useful Improvements in BundleBinding and Tying Machines, of which the following is a specification.

My invention relates to bundle tying machines of that class in which awire is drawn and secured taut about a bundle which may consist of anumber of articles of like kind assembled together, a box, or any kindof a package or bundle of limited dimensions about which it is desiredto secure a binding wire. 1

The object of the invention is to improve upon machines of thischaracter as formerly produced for doing the same or analogous work, andmore particularly to provide a machine comprising improved details ofconstruction such as adjustable tables for supporting the bundle,automatically operable toward and from clamping arms, means for holdingthe primary end of a wire strand while it is wrapped about the bundle,for twisting the end about the main strand, for cutting the strands, andmechanism for tucking the twisted ends beneath the taut band. It is alsoan object of the invention to provide a machine of this charactercomprising mechanism which will operate automatically, after the machinehas been started, to actuate the parts above mentioned in propersequence and to stop the machine at the end of one complete cycle ofoperations. In the accompanying drawings I have shown my invention asdesigned for bundling or tying up box shooks, the same bel ing oneimportant field of its use, although the device may be used in tyingbundles of various other articles. The drawings show the constructionwhich I now prefer to employ in a machine for this special purpose. l5,Figure 1 is a front elevation of the machine, all the parts being shownin their initial or starting positions.

Referring more in detail to the drawings:

1 designates a base whereon the operating parts of the machine aremounted, the same being somewhat rectangular in shape and is providedwith an edge flange whereby the horizontal portion is somewhat raised.

Mounted at the two rear corners of the base are spaced standards 2 and2', each provided with a base flange 3 secured by bolts 4;. Thesestandards carry the rotative annular rings by which binding wires areapplied and the mechanism mounted thereon at the point slightly beyondthe center of the base.

Mounted on the base 1, on a plane midway between the standards 22', andat each side of the point, are two standards 5, see Figures -8 and 9,each having a flanged base portion 6 for receiving anchor bolts 7, andhaving vertical channels or guideways 8 wherein posts 9 are movablymounted. Mounted on each of the posts 9 in horizontal alinement witheach other, are bundle, supporting tables 10 which when moved upwardco-operate with the horizontal portions 11 of arms 12 to compress abundle that may be supported thereon. The arms 11 and 12 constituteofl'set extensions of the standards 5.

The arrangement of the bundle supporting tables is such that a bundlemounted in position thereon for tying, will lie approxiraves mately inthe axis of the annular members supported by the standards: 2-,-2 andperpendicularly to the plane thereof.

The annular members, before mentioned, supported by the standards 2-2',comprise a central or stationary ring 15.which is hollow and rectangularin cross section and is ri idly secured to the standards by bolts 16,ring and standards and are drawn tight by nuts 16 to hold the ringrigidly in a. vertical plane.

Mounted revolubly on the exterior and interior of the ring 15respectively, are rings 18 and 20, the former having a toothed flange19, forming a spur gear and the latter having an annular toothed ring 21fixed to its forward edge forming a bevel gear, and a spur gear 22formed upon its rear edge.

Each of the rings 18 and 20 is revolubly supported, as by rollers 23,(Figure 24) mounted within the ring 15 and having peripheral flanges orribs extending thereigure' 5, which extend through the formed in thefaces of the rings. It is preferable to provide three rollers for thesupport of each ring andto space the rollers at 60 intervals startingfrom the top of the ring in such a manner that the central upper rollerand the two bottom side rollers support and retain the inner ring in'functional position, While the bottom and two upper side rollerssimilarly support and retain the outer ring.

In using the machine, the first step is to locate and clamp the bundlein position for wrapping. This is done by placing the bundle, which maybe of variable length, upon the tables 10 with one side edge against theguide standards l2.- Clamping o the bundle against the-horizontal arms11 takes place immediately after starting of the machine by a verticalmovement of the tables and the bundle is held in this position untilwrapping and tying has been completed. The means for doing this will belater described.

The mechanism employed for driving the revoluble members comprises, forthe outer ring, a gear wheel 26 which meshes with the toothed peripheralflange 19; the gear 26 is keyed on the shaft 27, which shaft issupported in bearings 2829 carried by brackets 30-31 that are fixed tothe standard 2'.

36, which is revoluble within the bearing 28 and upon the shaft 27 Eachring is individually driven from a pulley wheel 40 is freely revolubleon its mounting between the clutches when the machine is in neutralposition.

Assuming that the clutches are in neutral position, to start themachine, I have provided a foot lever 44 (Figures 3 and 6) which ispivotally supported from adjacent its rear end by a bolt 45 extendedinto the standard 2' and is yieldingly retained in a raised posltlon bya spring 46 fixed at its opposite ends to the base 1 and end of thelever.

Connected to the lever 44 by a pin and slot connection, as shown at 47,are links 48 which are pivotally fixed at their upper ends to an ear 49extending laterally from a cy- "lindrical sleeve 50 that is revolublymounted on a stub shaft 51 projecting from the standard 2'. At its outerend the sleeve is closed and has a pin 52 extending eccentricallytherefrom, which pin has connection with a horizontally disposedshifting bar 54, the latter being supported by and having pivotalconnection with, the lower ends of a series of centrally pivoted, clutchcontrolling and shifting levers 55, 56 and 57. The levers 56 and 57 areprovided with yokes at their upper ends which partially enclose the hubsof their respective clutches and have the usual connection therewith, sothat lon itudinal shifting of the bar 54 simultaneous y moves theclutches to engage one with and disengage the other from the drivingpulley, or to W place and retain both clutches in a neutral ordisengaged position, as the case may be.

The lever 55 is fixed to a rocker shaft 55' wherefrom -two arms 58 and59 are extended. These arms carry rollers 58' and 59 at their ends,which rollers are engaged at certain times during the operation of themachine by cams of such shape, and fixed at such position on therevoluble members, that they will rock the lever 55 to shift theclutches so as to thereby drive first, the outer ring and then theinner, and then to move both clutches to a neutral position to stop themachine at the end of a tying operation.

With the ,p'arts constructed as'so far described, it will be seen thatpressure applied at the forward end of the foot lever will cause thelinks 48 to draw downwardly on the ear 49 to partially rotate the sleeve50, which will, by its eccentric pin connection with the bar 54, shiftthe latter to thereby actuate the levers 56 and 57 to move the clutch 41into driving engagement with the pulley 40' and the clutch 42 away fromth1s pulley. Poweris thereby transmitted through the shaft ,27 to thegear 26 and the til latter starts the outer ring 18 revolving about thestationary ring andbundle.

Fixed to the forward face of the flange 19', which forms a part of thering 18, is a cam plate 64 having a somewhat abruptly indined cam trackmember 65 fixed thereto which, shortly after starting of the machine,engages with a roller 66 carried by a pivoted lever arm 66. This arm isshown as pivoted upon the forward end of the shaft 27, although there isno essential relation between the two.

Pivotally connected at its upper end with the arm 66, by a in 67, whichpin also serves to mount the rol er 66', is a rod 68, through whichadjustable connection is made with the outer leg 69 of a somewhatY-shaped lever that is pivotally supported by a shaft 70 between spacedbearings 71 formed on the base 1. The two legs 72 and 7 2' forming theinner part of the lever, extend to a point adjacent the lower ends ofthe two posts 9,

whereon the tables 10 are supported, and are connected with these legs,as by means of a shaft 73 which extends through the ends of both thelever legs and the posts.

With the connection described, when the outer ring starts to revolve,the cam surface 65 engages the roller 66 moving this end of the arm 66downwardly and outwardly so that it acts as a toggle link in connectionwith the rod 68, to rock the Y-lever and move upward the bundle whichwill be supported on the tables 10, into clamping engagement with theparts co-operating with the tables, as the retaining fingers 11.

As the arm 66 is rocked on its pivot to clamp the bundle, it moves to apoint slightly beyond the dead center, that is the line connecting thecenter of the shaft 27 .with'the lever 69, as shown in Figure 8,

so that the bundle will be retained in this clamped position until it ispositively released.

This releasing is effected by engagement of the forward end of the camplate 64 with a roller 74 at the outer end of an arm 74 that is formedintegral with the shorter arm 66, the two arms being,in such relationthat the arm 74 moves inwardly into a position that it will be engagedby the cam 64 as the outer ring hears a complete turn, while the arm 65is being moved outwardly 0n the initial movement of the ring. It isapparent that by forcing the arm 74 outwardly the arm 66 moves inwardlypast its dead center position, which allows the bundle supporting tablesto move downwardly to release the clamping pressure upon the bundle.

To provide an adjustment which will accommodate bundles of differentthicknesses, I provide means for adjusting the a reraeeo length of theconnection between the arm 66 and lever 69. As a desirable means fordoing this, I mount a sleeve about the lower end of the rod 68, whichsleeve has a threaded connection at its upper end with a threadedportion 76 of the said rod. wheel 77 is keyed to the sleeve so that thelatter may be revolved and thereby adjusted to different positions alongthe rod. The lower end of the sleeve carries a collar '78 wheretopivotal connection with the lever 69 is made, and at its upper end issplit and has a locking wheel. 79 with a tapered bore threadedthereover, to clamp the split ends of the sleeve against the rod andprevent rotation of the sleeve after adjustment.

The collar 7 8 bears against a coil spring 80 which surrounds the sleeveand rod, so

that yieldable clamping of the bundle is effected, and bundles ofslightly varying dimensions, within a certain limit such for instance asoccur in bundles which are nominally alike, may be taken care of withoutre-adjustment of the connection. For the accommodation of largervariations, adjustment of the sleeve on the rod is made.

After a bundle has been placed in position and the machine has been .setin motion by a downward movement of the foot lever, the first operation,as has been described, is the clamping of the bundle by the movement ofthe tables 10, but as the outer ring continues to revolve a wire ispassed around the bundle, as will now be described.

Mounted on the ring 18 is a reel wherein a supply of wire 86 is wound,the wrapping end of the wire being passed from the reel through atensioning device,'shown in Figures 25 and 26, which comprises a seriesof offset sheave wheels 88 fixed to a plate 87 that. is secured to the.face of the cam plate 64. After passing over a guide wheel 88 the wireis extended to and held by a twister head carried upon sleeve 90 that isfixed to the front face of the stationary ring 15. \Vith the wiresecured in this way it will be seen that as the outer ring revolves, thewire will be paid out from the reel and wrapped about the bundle. Thereel is retained in position by means of yieldable stops 910 (Figure 26)which extend outwardly from blocks 920, that are secured to the ring 18,so that the projecting ends of the pins engage the outer side face ofthe reel sufficiently to retain the in Figure 24, which engage adjacentfaces of the two members.

The wiretwisting head and cutting member which retains one end of thewire during wrapping, is shown in relation to the other parts in Figures1, 11 and 12 and separately in detail in Figures 14, 15 and 16. As thisis substantially like a device shown in another application to be filedby me, it will be herein referred to only generally. This twister headcomprises mainly a short rotatable tubular section 90 provided at itsinner and outer ends with bevel gears 91 and 92, respectively, and isrevolubly mounted within a semicyclindrical sleeve 93 fixed to a block94 which in turn is rigidly fixed to the ring 15 by bolts 95.

The semicylindrical tube 93 has projecting ends on which are turnedholding and bearing flanges 93. The bodies of gears 91 and 92 havecomplemental bearing and holding flanges 91 and 92 which pass outside ofand engage the flanges 93, thereby securely holding the cylinder 90 andits parts in place. The flanges 91 and 92 are continuous throughout thecircle, except for the wire receiving slot hereafter described.

The tube 90 is preferably mounted in such a manner that the line of itsaxial center lies in a plane which includes the axial center of the ring15. This is dictated chiefly by the simple bevel gear construction ofthe operating means which may be used when so located. a

Fixed to the inner end of the rotative head 90 is a plate 98 which has awire receiving slot 99 therein registering with a like slot 100extending longitudinally of the head. A toothed wire cutting wheel ordisk 101 is journaled at 102 in the plate 98 at one side of the axis ofthe'twister parts. This wheel 101 has a series of recesses extendinginwardly from its periphery, the sides of which form cutting memberswhich, when the wheel is turned 00- act with the plate 98 to form wirecutting shears. The'axis of the wheel 101 is so located that the bottomof the groove therein as it is turned will be brought into registry withthe axis of the head 90.

The projecting portions between the recesses function as teeth byengagement therewith of a tooth 104 carried by a cam plate 105 which isfixed to the inner curved face of the inner revoluble ring 20, so thaton each revolution of the ring the cutter is revolved one tooth space,thus cutting the wire in the slot 99. The means for cutting theforereferred to or any other suitable mechanism. This should be such aswill securely holdit against the strain of putting the wire about thenext bundle.

At the start of an operation the parts are in the position shown inFigure 1. i The wire .has its end secured between the cutoff wheeltables 10. The movement of the outer ring is temporarily stopped whenthe wire has enclosed the bundle. this being at a time when the outerring has made approximately three-fourths of a revolution.

The means employed for stopping the outer ring at this particular timeconsists of a cam block 106 that is fixed to the back face of the outerring as shown in dotted lines Fig. 1, and diagrammatically in Fig. 4.This cam engages the roller 58 at the end of the arm 58, moving thelatter to rock the lever 55, to thus shift the clutches sufficiently todisengage the clutch 41 and move the clutch 42 into driving relationwith the pulley, so that at the time the outer ring is temporarilystopped, the inner ring starts revolving.

Mounted on the side face of the stationary ring at opposite sides of thetwister head, are wire clamping arms 108 and 109, whereby a wire wrappedabout the bundle is pressed against the bundle at opposite side of acorner and held so that the twister head may function properly. Theupper clamp-. ing arm 108 is actuated soon after the Wire has been drawnacross the top of the bundle While the lower arm 109 moves to clampingposition as soon as the wire is in position for twisting; both clampsbeing actuated to clamping position by engagement of the forward end ofa sector 110 that is fixed to the outer ring, with certain parts workingin conjunction with the clamping members. Operation of the clamps isillustrated in Figs. 11 and 12 and is as follows:

The clamp arms 108 and 109 are pivotally mounted on pins 111 and eachhave curved and laterally offset feet 112 which engage the wire to pressit down against the side of the bundle. These feet may be grooved ontheir under edges to retain the wire when they are clamped thereon; theclamps areso located that when moved to functional position, the feet112 clamp the wire against the bundle at the corner which is adjacentthe twister head.

Pivotally connected with each of the clamps are one end of links 114,the outer ends of which pivotally connect with rocker thereto. As theouter ring starts to revolve the forward end of the sector 110 isbrought into engagement with the roller 118 of the first clamp mechanismriding thereover and 'revoluble members 122 fixed to the stationary ring15. The springs bearing at their opposite ends against the rodmountings.

The outer ring stops at such a position that the wire, when pressedagainst the bundle by the clamp 109, will be moved into the slots 98 and100 of the rotatable head members to extend centrally therethrough andclosely adjacent the primary end of the wire.

Shortly after starting of the inner ring the twisting operation takesplace. This is accomplished by means of the revolving of the twisterhead to carry the secured end of the wire about the main strand, thehead being revolved by the meshing of the segment gear 21 carried by theinner ring 20 with the bevel gear 91 carried by the inner end of thetwister head.

After the Wire ends have been twisted together, the wire which extendsthrough the twister is severed, as before described, and the ends of thetwisted strands are drawn beneath the baling strand by means of a tuckermechanism particularly illustrated in Figs. 19 to 23 inclusive, therebyto strengthen the tie and also give protection to workmen handling thebundles.

The tucker mechanism is supported by a bracket 125 which may besupported from one of the standards 12. The tucker comprises a curvedfinger 126 pivotally mounted on a shaft 127 to which shaft is secured agear pinion 128 with which engages a rack bar 129, that is slidablymounted in the bracket to thereby oscillate the finger 126 on its pivot.The end of the rack has a roller 130 mounted thereon which is adapted topass within a cam slot 131 in the plate 105 carried by the innerrotative ring 20.

The position of the finger 126, while the wire is being passed about thebundle and until cutting is done, is shown in Fig. 20. This shows thewire drawn across the finger and extending between its end and itsivotal point.

As the cam 105 moves forward, the rack roller 130 passes into the slot131 at the end which is uppermost in Figures 20 to 28 and a curve 132therein carries the rack rearof the cam slot, moves the finger again toinitial position as the cam disengages the roller.

While the tucker is in operation the twister head remains stationary,this being due to the fact that during this time a blank or untoothedportion 135 of the ring 21 is passing by the twister head. The cam 105is fixed to the blank part of the geared ring 21 so that the cutting ofthe wire and tucking of the twisted ends starts as soon as twising iscompleted.

As the inner ring continues to revolve, cams 140141 engage respectivelywith the rollers 119 of the upper and lower rocker members .to actuatethe same sufficiently to swing them past the dead centers, whereupon thesprings 120 will move the clamps back to open position.

As the inner ring approaches a complete revolution, a cam 146 carriedthereby, shown in Figs. 1 and 4, engages the roller 59. of the lever 59.Again rocking the lever 55 to move the clutches back to their firstdriving position, to stop revolving the inner ring and resume driving ofthe outer ring, so as to bring the latter back to its initial position.The machine is then stopped by engagement of a cam 175 (Figs. 1 and 4)with the roller 58 on the lever 58 which shifts the clutches 41 and 42to neutral position.

It will be mentioned here that during the time of operation of thetucker, the twister head remains in such position that the slot 100faces outwardly, but, just prior to final turning of the outer ring, thetwister head is given three-fourths of a turn by means of a short gearedportion 148 immediately ollowing the blank portion 135, so by engagementof its inner gear 92 with the segment gear section 148, whereby the slot100 will face in the direction of travel of the ring and the wire maypass therefrom, but at the initial movement of the outer ring on afollowing tying operation, the head is given one-half revolution by ashort toothed section 150 carried by the sector 110 and engaging thegear 92, so that the head will be in position to receive the wire as itencloses the bundle.

When a shift of the clutches is made from one extreme to the other, itis desirable that the released clutch be stopped as quickly as possibleand this is accomplished by mount ing friction blocks 152 adjustably inthe brackets 29-30 against which the clutches are moved when shiftedfrom driving relation with the pulley wheel and the frictional contactcauses almost immediate stoppage of rotation.

The clutches, when occupying released, driving or neutral position, areyieldingly retained 'in such set position by means of mechanismparticularly illustrated in Figs. 4, 6 and 7. This mechanism comprises aspring plate 155 which is fixed at one end in a bolt 156 that is mountedin the standard 2 and at its opposite end has a rib 157, adapted to seaton opposite sides of or within the grooved end of a post 158 that isthreaded into and extends downwardly from a collar 159 revolubly mountedon the pivotal supporting shaft of the clutch shifting lever 56, and atits lower end extends slidably through a horizontal pin 160 that isrevolubly any mounted between spaced arms 161 extending upwardly fromthe sleeve 50, fixedly secured relative to the clutch shifting lever 54.A spring 162 surrounds the post 158 and bears against the collar 159 andpin 160 with sufficient pressure to .hold the clutches in drivingcontact when shifted to either posi-' tion.

lVith the parts of the machine constructed and assembled as described itis apparent that an operation will be started by pressure on the footlever which moves the clutch 41. into driving contact to revolve theouter ring. Revolving of the outer ring causes, first the bundle to beclamped in position, second the wrapping of the wire about the bundleand actuation of the clamping arms to press the wire against the bundle.The clutches are then shifted by the cams 106 and the inner ring startsto revolve. This causes the twister head to rotate to twist the wire andas the cam 105 moves past the twister head and tucker it actuates thewire cutter and tucker, on final movement of the ring the clamps arereleased and the twister head turned to such osition that the wire maypass therefrom. inal movement of the outer ring brings the cam 17 5 intoposition to shift the clutches to neutral position to stop the machinesimultaneously as the cam 65 moves into functional position to releasethe bundle from clamped position.

When one wire has been placed about the bundle and secured, the bundlemay be moved along to have another wire placed about it and this berepeated as often as necessary. The bundle is moved in the same forwarddirection when putting it into the machine, shifting for addingadditional ties and in taking it out of the wheel.
